[Colab] Error on Accompaniment and vocal separation

When I try to process accompaniment and vocal accompaniment separation I get the following error message:

.ipynb_checkpoints.reformatted.wav->Traceback (most recent call last):
File "/usr/local/lib/python3.10/dist-packages/librosa/core/audio.py", line 164, in load

soundfile.LibsndfileError: Error opening '/content/Retrieval-based-Voice-Conversion-WebUI/TEMP/.ipynb_checkpoints.reformatted.wav': System error.

The same happens if I select HP2 or HP5 model.

Reproduce the Colab accompaniment and vocal-separation flow with the HP2 and HP5 models, starting from the librosa/core/audio.py:164 traceback and the TEMP/.ipynb_checkpoints.reformatted.wav path. Trace how that WAV path is produced and determine what change is needed so librosa can open it successfully.
